Solution Overview

Problem

Existing bow sights face challenges in enhancing sight point visibility, particularly for longer fiber optic members, which require innovative configurations to collect and reflect ambient light effectively.

Innovation Solution

The use of a pin configuration with a fiber optic cable or strand, a one-piece shaft, central portion, and spool, which is vertically adjustable and includes tick mark members to enhance sight point visibility, allowing for independent adjustment of multiple pins for various target ranges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If longer fiber optic members are used to increase sight point brightness, then the sight point visibility is improved, but the device complexity increases due to the need for special wrapping configurations

Engineering Contradiction:
Improvesight point brightnessVSAvoidwrapping configuration complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The fiber optic member is divided into multiple segments or sections, each wrapped around its own spool. This segmentation allows each segment to be independently managed and wrapped, reducing the overall complexity of the wrapping configuration while still achieving the benefit of longer fiber optic members for increased brightness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fiber optic member is wrapped around spools in a three-dimensional configuration rather than being laid out in a simple linear or planar arrangement. This dimensional change allows the fiber to be compacted efficiently while maintaining its length, reducing the space and complexity required for wrapping.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple sighting members are added to cover different target distances, then the versatility is improved, but the device complexity increases

Engineering Contradiction:
Improvetarget distance coverageVSAvoidnumber of sighting members
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each sighting member is designed with universal functionality to serve multiple purposes. The sight pins can be adjusted vertically to correspond to different target distances, allowing a single pin structure to perform multiple functions that would otherwise require multiple specialized components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The sighting members are made adjustable rather than fixed. The vertical adjustability of the sight pins allows the archer to dynamically reposition them to match different target distances, providing versatility without requiring a fixed complex arrangement of multiple permanently positioned sighting members.

Inventive Principle:
Principle #15Dynamics

3Use of energy by moving object

If fiber optic members are wrapped in complex configurations to accommodate longer lengths, then the light collection capability is improved, but the ease of manufacture decreases

Engineering Contradiction:
Improvelight collection capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Use of energy by moving objectVSEase of manufacture

Solution Approach 1:

The manufacturing process is simplified by dividing the fiber optic member into segments that are wrapped around individual spools. Each segment can be manufactured and wrapped independently, making the overall manufacturing process more manageable and less complex than creating a single long wrapped configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Spools are introduced as intermediary components to facilitate the wrapping of fiber optic members. These spools serve as simple mechanical aids that make the wrapping process easier and more standardized, improving ease of manufacture while still achieving the desired light collection capability through adequate fiber length.

Inventive Principle:
Principle #24Intermediary (Mediator)
